Overview

Zeitwerk is an innovative and efficient code loader designed for Ruby, catering to the needs of developers who require a seamless loading experience for their classes and modules. It simplifies the process of managing dependencies by allowing autoloading - loading classes on demand - as well as eager loading, which preloads all necessary classes upfront. The structured approach it offers, along with thread-safety, makes it an attractive solution for modern Ruby applications and gems.

With Zeitwerk, developers can focus more on their code without worrying about excessive require calls, as the gem intelligently handles loading based on the project's directory structure and naming conventions. This leads to a more streamlined development experience, particularly for those working with Rails applications or similar frameworks where dependency management can become cumbersome.

Features

Efficient Loading: Zeitwerk efficiently loads classes and modules on demand or all at once, allowing for flexibility in how code is structured and accessed.
Thread-Safe Operations: The gem ensures thread safety during code loading, which is crucial for web applications that run multiple threads.
Independent Loaders: Multiple Zeitwerk loaders can coexist within the same application, each managing its own project tree independently.
Automatic Namespace Management: Classes and modules are automatically linked to their respective namespaces based on the directory structure, minimizing manual requires.
Code Reloading Capability: Zeitwerk supports code reloading, enabling developers to make changes and see them reflected instantly during development without restarting the server.
Custom Inflectors: Users can define custom inflectors to manage the naming conventions in their projects, providing greater flexibility in handling different naming styles.
Logging Features: Built-in logging capabilities help track loading behavior and can assist in debugging issues related to class loading.
Single Scan of Project Tree: Zeitwerk performs a single scan of the project tree, optimizing the loading process and reducing unnecessary file system lookups.
